Soil Parameters for jet-grouted Alluvium Soil
Soil Parameters for jet-grouted Alluvium Soil
(OP)
Does anybody know were I can find soil parameters (internal friction - cohesion - bearing capacity ...) for jet grouted soils?

RE: Soil Parameters for jet-grouted Alluvium Soil
As per the stability analysis for a small dam with 15 m high;
the following soil parameters seem to be enough:
bearing capacity: 300 kPA
coefficient of frinction: 33 degree
cohesion:100 kPa
At this point, how can I specify the jet grouting parameters?
I read some papers related with the subject, they are not clear enough.
A good referance is better answer.

not too deep or with geophysical methods ( electrical cylinder mainly). For the strength, you just sample the spoil which has the same composition than the column and you test it just like grout or concrete.

Remember that for a dam's stability, you may need the jet grout to provide lateral resistance in addition to bearing capacity, which requires high strength on horizontal surfaces under the slopes. Therefore, any continuous weak horizontal layers could be a problem for a dam, even if they are not such a big deal for other structures that just need bearing capacity or control of settlement. This is not as easy to accomplish. You may also need good column overlap to be able to mobilize the lateral resistance (complementary shear on vertical surfaces).
Use Google etc. to search for papers on jet grouting at Tuttle Creek Dam, Kansas, and Wickiup Dam, Oregon, which were modified for earthquake problems.
